5 Claims.

My invention relates to a paint striping unit and is a modiication and improvement of my former device described in my patent application Serial No. 675,594, led June13, 1933.

The object of my invention is ing unit adapted for maki nished painted surfaces.

Another object is to produce a special paint striping device of simple construction having both the striping unit and paint chamber within a singe unit casing, adapted for owing paint to the striping unit in various positions.

A further object is to produce a striper device of a construction adapted for single or multiple striping units mounted therein, each capable of producing a separate striping line when contacted and displaced by an engaging surface.

A still further object is to produce a striping device with special guard operating units, designed to function to start or cut a line at chosen points.

These several objects are attained in the preferred form by the construction and arrangement of parts more fully hereinafter set forth.

Similar parts on all drawings are marked by similar numerals or letters.

In general, my striping device comprises an elongated hollow casing member having a guide frame xedly mounted on one end thereof, designed to engage some pre-determined form of guiding template, and adjustable paint striping nibs slidably mounted within the casing member and projected therefrom, through the guide frame section end, at chosen positions, theguide frame being provided with an adjustable guard for the striping units.

I will now describe more fully the detailed construction of my device, referring to the drawings and the marks thereon, describing more specifically the single striping unit type as shown inV Figs. l to 7 of the drawings, also with the multiple unit type as shown in the Figs. 8 to 14 as a modiiication thereof. 40

The casing I is made of metal, either cast or turned, and preferably formed in an elongated hollow, tubular body sectionv a, open at one end and provided with internal end threads b formed therein, the opposite casing end being formed 45 with an. internally threaded neck section c, and which carries a casing cap 2 threadably mounted therein. Thecasing cap 2 is preferably formed with. a small air vent opening 3 therethrough, opening intov the casing chamber A, but which 50 may be closed, when desired, by the small cap disc 4 pivotally mounted on the, cap top. The open end of the casing I is threadably mounted on a head block` 5, engaging a threaded collar g to the respective strip- E provided thereon, uniting` the two sections as 55.

the outer end `a single solid member.

Through the center of the head block 5, inside the casing l, is mounted an elongated slide block l, fixedly and rigidly attached thereto, and positioned Vat right angles to the head blockface, concentric' with the casing axis, said slide block being extended nearly the entire length of the casing chamber A. Through the center of the slide block Yi is formed a cylindrical slide channel 8, extending the full length thereof, said channel being positioned concentric with the casing axis and formed with a short rectangular slide section d near the inner end thereof, and carries slidably mounted therein a Vslide rod 9, also formed with a like rectangular slide section e thereon, suitable to Vengage and t the channel slide d, yet slide freelyV therein, the rod slide e being slightly longer than ,also carries a circular contact washerV i3 and a compression coil spring lli mounted thereon, positioned Vto engage the shouldered end of the casing slide d, and carries xedlyV mounted on thereof a tubular paint striping nib l I which also engages the coil spring I4, causing Vsaid spring to function whenV properly stressed, for retaining the assembled strper unit B in its extended closed position as shown in the Fig. 5 of the drawings, the stop nut lll operating as a stopping means for the striper unit when adjusted to the slide channel ends. YThe striper nib Il is preferably made ofthe type and design as shown and described in my former patent ap- 1 plication, Serial No, 484,283, filed Sept. 25, 1930, and is applied herein to villustrate any type of striping nib unit as may be adaptable to this type of striping device. The nib l l herein shown,

comprises a hollow, cylindrical casing 'f of a diameter for slidably mounting same within the' slide channel, and is formedwith a circular disc recess g at the outer end thereof, and which carries a thin, circular marking disk h rotatably mounted therein, but positioned with the disc Vedge projected outside the inclosing casing end.

The casing channel K being extendedfrom the disc recess g, aximetrically therethrough to the oppositecasing end, and receives the end of the slide rod 9 fixedly and securely fitted therein, forming a rigid and continuous striping unit B. When a wide striping disc h is used, it is desirable to mount a paint retaining disc spring l2 within the disc recess y, and which partially incloses the marking disc h, contacting the disc edges, and functions to remove any excess paint from the disc edges as it is rolled along a painted surface, designedto prevent running of newly painted stripe lines. The specific structure of this type of paint striping'nib is fully described in patent application last previously mentioned.

with the slide channel port p, only the striper unit B is longitudinallydisplaced within the slide channel 8, by applying pressure to the extended striping disc edge while using thev device on a painted surface, Said displacement of the strip- Vterminating the stripe lines ing unit B automatically opens the liquid paint passages from the paint container chamber A of the casing l directly into the nib chamber K, and when the pressure isfreleased on the strip-A ing unit disc h, the compression coil spring I4 5 will close the paint passages'by a return displacement of the striper unit. Y

The head block 5 may be extended to any required design or formation, for forming a guidingunit for the striper, depending upon the type 10 and structure of template with which it is to be used, and is herein illustrated as being formed with an extended guide rib r along one edge thereof andn provided withcontact guide groove and slide s and t, designed to engage and fit spe- 15 cial template guide slide bars u and u respectively, as indicated by the dotted sections in Fig. 1 of the drawings. However, any type of striper guide members may be used. Y

Through the head block 5 are formed parallel 20 slide grooves l5 and I6, positioned parallelto the Y guide contact surfaces s and t, and carry slidably mounted therein a guard slide frame C, formed Y of parallel slide rods I1 and head bar I8 xedly attached thereto. Compression coil springs I9 25 are mounted on the slide rods I1 and engage the edge of the head block 5, designed to displace said guard frame away from theY head block when released. Through the center of the head barV i3 is mounted a curved flexible spring bar 2E! hav- 301 ing its free end positioned near, and at one side of the striping disc edge h, so as to engage and cover the disc edge when theguard frame C is displaced toward the head blockV 5 by pressure Y applied thereonagainst the slide springs i9, thus 3-5 preventing thestriping dischl from operating. This guard unit provides means for cutting and at any chosen point along theV template, by providing proper template stops thereon for engaging and displacing the 40S guard unit beneath the striping disc, or to allow i a definite starting of the line when operated in the reverse direction, the paint chamber A being previously filled with liquid striping paint by removing the casing end cap 2. The striperis used 45 in the ordinary manner.

A modified form of my striping device is illustrated in Figs.'8 to 14 of the drawings, applying multiple striping units B therein instead of theY single striping unit previously shown. The s1ide150 block la is formed with three parallel slide chan- Y nels 8a., positioned one above the other as illustrated in Figs. 8, 9 and 10. The structure of each striping unit B is exactly the same as in the former typeheretofore described for the 55 singleunit, each functioning and operating independently of the other, designed to produce slightly irregular. The respective slide channel 50 ports Sw may be formed in the slide block la. in the same manner as inthe former case, cach opening separately into the casing paint chamber A by separateV passage channels as illustrated c. in thelFig. 13, or as is shown in the Figs. 8 and 9, 65 comprising a continuous vertical passage channel, open when all striping units B are displaced simultaneously within the supporting slide block. The remaining structure and operation Vis the same as heretofore described. In all'cases, the 7() tubular casing I forming the paint chamber'A, Y completely Vincloses the striper unit slides at all times, and provides a steady ow'of paint to the striper nib chamber K for nearly all positions of the striping device. 7 5" When the striping device is to be used continuously in one position, an added paint reserve tank 2| may be mounted on the top side of the casing, opening therein as illustrated in Fig. 12 of the drawings. 'I'his serves to increase the paint capacity, and to retain the paint chamber A full at all times, insuring a continuous paint iiow for all positions of the striper device. The Fig. 14 illustrates a modication of the reserve tank mounting, where the tank neck is extended to open directly into the slide block channel ports p, each striping unit B being provided with a separate channel passage leading thereto. The remaining structure and operation is the same as.

in the former case.

It is apparent that my device is adapted to various modications in both structure and detail design, and without departing from the spirit of my invention, and I claim the striping device as herein illustrated and any modification thereof that is substantially a substitution of parts herein shown.
